Sixteen-year-old Wisteria has embraced her deep bond with eighteen-year-old Bach, a member of a supernatural race called the Family, despite the risks. Should his people discover his bond with a human, Wisteria will be guaranteed a painful and bloody deathâbut somehow, being together is more important.

Their bond is tested when empirics, an elite group of Family investigators, are sent to the Isle of Smythe under the orders of Bachâs father to find artifacts stolen by the humans. Theyâre to find the artifacts at any cost. Among the empirics is Bachâs old friend, the stunning Alba, who has learned about Bach and Wisteriaâs secret relationship, and surprisingly accepts this. With no one else in the Family to turn to, she becomes Bachâs ally and confidant, but possibly more.

As the empirics start to take over the town, Wisteria is torn between trusting Bach and the safety of the humans on Smythe. She soon realizes that she and Bach are on opposite sides of the war between the Family and Humans, and there is no middle ground. One of them must choose a side.
